The correct order of basicity for the following molecules is $:$

The diazonium salt of which of the following compounds will form a coloured dye on reaction with $\beta$-Naphthol in $NaOH$?

Which of the following is the weakest base?

What is the end product of the following reaction sequence?
$CH_3CH_2NH_2$ $\xrightarrow[H^+]{KMnO_4}$ $\xrightarrow{SOCl_2}$ $\xrightarrow[\Delta]{NH_3}$ $\xrightarrow{NaOH/Br_2} ?$

Match List-$I$ with List-$II$:
Benzenediazonium chloride $(C_6H_5N_2^+Cl^-)$ is reacted with reagents in List-$I$ to form products in List-$II$.
| List-$I$ (Reagent) | List-$II$ (Product) |
| :--- | :--- |
| $A$. Aniline $(C_6H_5NH_2)$ | $I$. Fluorobenzene $(C_6H_5F)$ |
| $B$. $HBF_4, \Delta$ | $II$. Benzonitrile $(C_6H_5CN)$ |
| $C$. $Cu, HCl$ | $III$. $p$-Aminoazobenzene $(C_6H_5-N=N-C_6H_4-NH_2)$ |
| $D$. $CuCN/KCN$ | $IV$. Chlorobenzene $(C_6H_5Cl)$ |
